Unless we can have a proper test for that, it's difficult to tell. Compare the situation of a young high school athlete. May have all the right athletic skills and attitude. But perhaps that attendance into some special skills development camp is just what they needed to push themselves over the edge to the next level. It can't hurt that they're attending together with other young top athletes who will push each other forward. Aside from that, one of the only reason I'd ever attend an MBA school if I ever wanted to, was to easily develop a network of top-level A-players. It's easy to develop the network like that when top people are grouped together in the same place with the same goals. A top-tier MBA school is not the only place where you have that situation, but I imagine that it is one of the only places. That being said, there are a lot of reasons to not get an MBA, especially if it would not contribute at all to your goals.
